Scientists in Norway have more good news for coffee drinkers. Researchers have already found evidence that the drink -- or the beans it's brewed from -- can help with weight loss , reduce one's risk of developing Alzheimer's disease or dementia, boost muscle growth , protect against certain types of cancers, and can even reduce one's risk of premature death , among many other benefits . Now comes word that a cuppa joe reduces physical...

SEATTLE - The long-running detective saga involving one of North America's earliest inhabitants has taken a new twist, with news that Kennewick Man - the shockingly intact 9,300-year-old skeleton unearthed in 1996 on the banks of the Columbia River - probably was a visitor to central Washington, not a longtime inhabitant. More likely, Smithsonian Institution anthropologist Douglas Owsley announced in a pair of lectures this week in Washington state, he came from the coast, not the arid inland valley where his remains were found.

Screaming at your teenagers to discipline them can make their behavior worse - even if you otherwise have a warm family relationship, researchers say. The effects were comparable to those in studies that focused on physical punishments, the researchers said. “From that we can infer that these results will last the same way that the effects of physical discipline do,” the lead researcher, Ming-Te Wang, an assistant professor of psychology in education at the University of Pittsburgh, said in a statement.

Up and down the West Coast, starfish are dying. Casualties of a mysterious disease known as seastar wasting syndrome, they are dying in Alaska, deteriorating in San Diego and disappearing from long stretches  in between. Death from the disease is quick and icky. It begins with a small lesion on a starfish's body that rapidly develops into an infection the animal cannot fight. Over the course of the disease the starfish's legs might drop off, or even separate from the body and start to crawl away, as you can see in the PBS news story below.

Scientists have figured out how to grow human stem cells into "cerebral organoids" - blobs of tissue that mimic the anatomy of the developing brain. The advance, reported online Wednesday by the journal Nature, won't allow scientists to grow disembodied brains in laboratory vats, said study leader Juergen Knoblich, a stem cell researcher at the Institute of Molecular Biotechnology of the Austrian Academy of Science in Vienna. But it does offer researchers an unprecedented view of human brain anatomy, he said.

The dark dust thrown up by human activity in the deserts of the Southwest hastens the melting of Rocky Mountain snow and ultimately reduces the amount of water flowing into the upper Colorado River by about 5%, scientists reported Monday. The lost water amounts to more than 250 billion gallons — enough to supply the Los Angeles region for 18 months, said study leader Thomas H. Painter, a snow hydrologist at the Jet Propulsion Laboratory in La Cañada Flintridge. "That's a lot of water," said Painter, whose study was published online by the Proceedings of the National Academy of Sciences.

A team of storm-chasing scientists sampling rarefied air has found a world of bacteria and fungi floating about 30,000 feet above Earth. The findings, detailed Monday in the Proceedings of the National Academy of Sciences, suggest that microbes have the potential to affect the weather. Scientists have long studied airborne bacteria, but they typically do so from the ground, often trekking to mountain peaks to examine microbes in fresh snow. Beyond that, they don't know much about the number and diversity of floating microbes, said study coauthor Athanasios Nenes, an atmospheric scientist at Georgia Tech.

Is 2012 the end of the world? If you scan the Internet or believe the marketing campaign behind the movie "2012," scheduled for release in November, you might be forgiven for thinking so. Dozens of books and fake science websites are prophesying the arrival of doomsday that year, by means of a rogue planet colliding with the Earth or some other cataclysmic event. Normally, scientists regard Internet hysteria with nothing more than a raised eyebrow and a shake of the head. But a few scientists have become so concerned at the level of fear they are seeing that they decided not to remain on the sidelines this time.

A group of scientists warned Tuesday that world leaders must act more swiftly to slow greenhouse gas emissions or risk "abrupt, unpredictable and potentially irreversible changes" from climate change. The American Assn. for the Advancement of Science's blunt report contains no new scientific conclusions. But by speaking in plain, accessible terms it seeks to instill greater urgency in leaders and influence everyday Americans. Scientists said many previous assessments have been long and ponderous, and have failed to shift public opinion on global warming.

In August, NASA's Mars Science Laboratory will reach the Red Planet and begin its search for habitats that could have supported life. The next-generation rover, better known by the nickname Curiosity, will pick its way up a mound in the middle of Gale crater and look for evidence that water once flowed on the Martian surface - a condition that is considered a prerequisite for hosting microbial beings. On an expedition to the California desert this month to demonstrate some of the challenges Curiosity will face on Mars, scientists chatted about the upcoming mission.
